3 General Information
The S6 is the first model of a whole new handset generation in 3 Volt technology.
It comes either as a GSM or a PCN version.
4 Mechanical Concept
Note: All part numbers refer to mechanical drawing in section 4.1!
The S6 consists of two boards, the RF & Control module (1010) and the user
interface (1020).
The connection between those two boards is not made by a normal connector with
plug-in contacts, but by a special interconnector (1090) embedded into a shielding
frame (1060). This interconnector is upholding the connection through the pressure
implied on it by the housing.
Be careful when assembling the interconnector. Avoid any kind of dust or dirt
because it will affect the contacts of the interconnector.
The only removable part on the user interface is the ringer gasket (1080) which is
needed to increase the ringer volume.
Furthermore there is a RF-plug on the user interface which has to be plugged into the
appropriate connector on the RF & control module. This conection is very essential
because it is the RF signal from / to the internal antenna.
The shielding is done by the lower case shell (1050) which is covered with a
conductive material, so no additional shielding screen is necessary.
The antenna (1130) is directly screwed into the lower case shell.
The keypad (1030), the loudspeaker (1120), the microphone (1110) and the dust
protection frame (1210) are mounted into the upper case shell (1040). Make sure that
the microphone contacts are properly bent up when mounting.
When turning in the screws (1140, 1145 and 1150) make sure that the right torque is
used (25 Ncm), because this will have an effect on the contacts of the interconnector.
Note: Make sure that you mount the right antenna, the GSM antenna has two
stripes, the PCN antenna only has one!

4.4 Board Versions
In the S6 mechanical drawing you see a bolt (position 1220) which is holding the
RF&control module and the user interface together. This bolt was mounted only in
the first 100k S6 handsets produced.

V1.3 9 PN MP ST

The handsets produced later are using different board versions with different part
numbers (see table below!)
If a bolted handset comes back for service and one of the boards is defective, do not
try to separate them. Just send the whole sandwich back to Germany.
Attention!
These numbers are not the spare part ordering numbers, they are manufacturing
numbers printed on the boards itself.
Do not use them for ordering spare parts!

4.5 Upper Case Protection
If the bolted boards are used, it
has to be made sure that one
guiding pin in the upper case
shell is removed (see drawing!).
If the pin is not removed, the case
may break!
Attention!
Do not remove the pin if the
unbolted boards are used!
The removal of the pin is simply
done by cutting it off with a sharp
knife or cutter.
4.6 Handset Datecodes
Siemens is using the industrial standard DIN EN 60062 to indicate the production /
service dates. The code is printed on the IMEI sticker located under the simcard
reader.

J = 1997
The second character indicates the month of production:
1-9 = january to september

5.2 Hardware Description
The handset consists of five major integrated circuits:
1)
GOLD-µC (PMB 2706)
This microprocessor is responsible for controlling the keyboard, SIM-Card, EEPROM,
Flash and RAM.
Furthermore it interfaces the GOLD-SP (PMB 2707), controls the power up/power
down of the RF module and sets the amplification of the PA.
2) GOLD-SP (PMB 2707)
This signal processor is responsible for processing the Rx I/Q signals (filtering,
equalizing, speech and channel decoding).
Furthermore it does the speech and channel encoding and the GSMK modulation of
the Tx I/Q signals.
3) GAIM (PMB 2905)
The GAIM provides the interface between the analogue signals (I/Q, voiceband, PA-
control) and its digital representation.
4) Receiver Circuit (PMB 2405/07)
This circuit provides the following main functionalities:
a) Low Noise Amplifier (LNA) with a fixed amplification of +20dB to amplify the input
RF signal.
b) Mixer to mix down the RF signal to the Intermediate Frequency (IF)
c) Programmable IF amplifier with a dynamic range of 60dB ( -10dB ... +50dB in
steps of 2dB)
d) Mixer to mix down the IF signal to the baseband, generating and inphase (I) and a
quadrature (Q) signal.
e) Offset compensation for the I/Q signals.
5) Transmitter Circuit PMB 2240/45
This circuit provides the IF synthesizer, the I/Q modulator, prescalers to regulate the
RF synthesizer and a buffer stage to feed the PA.

The antenna switch is mechanical, whenever you plug in the bottom connector, the
handset will switch to its external antenna.
5.3 Power Supply Concept
The S6 has two main power inputs (see Blockdiagram):
1) Battery Voltage (3.6 Volts) connected at the battery contacts
2) Charging Voltage (6.5 Volts) delivered by
a) The plug-in charger at the charging plug
b) The desktop charger (using the charging contacts at the bottom of the phone)
Since the battery voltage is supplying the power supply asic, it is always needed to
operate the phone. You cannot switch on the handset if the battery voltage is not
present.
From the 3.6 V battery voltage, all other supply voltages of the S6 are derived,
controlled by the power supply ASIC.
The RF module needs 6.4 V for its PA, this voltage is generated by a step-up
converter.
The logic module uses 2.8 V, generated by a simple linear regulator.

Furthermore the ASIC generates the supply voltage for the SIM-Card and the RESET
signal for the logic devices.
The ASIC also checks the presence of the watchdog signal from the µP and provides
the switching on functionality (ON_OFF button or Ignition signal).
During testing ist is advisable to use a battery dummy, connected to a power supply
delivering +4V, max 3A.
Make sure that you connect the battery dummy with the right polarity, the red plug to
+4V and the blue plug to ground.
If you use a voltage higher than +7V, or with wrong polarity, the phone can be
destroyed!
5.4 Overvoltage Conditions
a) Battery Voltage: If the battery voltages rises above 6.2 Volts, the phone will
switch off and it cannot be switched on again before the
voltage is lower than 6.2 Volts.
If the battery voltage rises above 7 Volts the phone can be
destroyed.
b) Charging Current: The charging current must not rise above 1 A or the
phone (fuse) will be inoperable.
-> Be careful with foreign accessories or chargers!
-> Make sure that the charging current is limited to a value below 1A!
